MAGAZINE-SHIFTING MECHANISM FOR TYPOGRAPHICAL MACHINES.

Specification of Letters Patent.

Application filed August 24, 1920. Serial No. 405,700.

T 0 all whom it may concern:

Be it known that I, THOMAS a citizen of the United States, residin at Hempstead, Long Is. in the county of l assau and State of New York, have invented new and useful Improvements in Magazine- Shifting Mechanism for Typographical Machines, of which the following is a specilication.

My present invention relates to improvements in typographical machines, and more especially to those of the linotype class, wherein the matrices which are adapted to be assembled into lines for the casting of type slugs therefrom, are stored in a magazine or magazines, from which they are delivered, as required, by the operation of a keyboard. The herein described improvements are directed more particularly to machines of the class described, which are adapted to contain a plurality of matrix storage magazines, arranged in superposed relation, any of which magazines may be brought into operative position to deliver matrices therefrom, as required. My prior Patent No. 1,156,031, granted October 5, 1915, shows and describes a magazine supporting or shifting structure which enables any one of three superposed matrix magazines to be easily and quickly brought into operative position to deliver matrices therefrom, and the structure shown and described in said patent is in practice, a substantial improvement upon other magazines supporting and shifting structures'of the same kind which preceded it. The structure shown and described in my said patent, however, makes it necessary for the operator to lo ve his seat at the keyboard of the machine, in order to operate it to shift the magazines, and furthermore, the magazine shifting handle of that device woiild'iiiterfore, in its movements, with a side attachment placed at the adjacent side of the machine, such, for example, as the sidemagazine attachment shown and described in my prior Patent No. 1,321,744, granted November 11, 1919.

The primary objects of the present inventionv are, to provide a novel and improved structure of the class hereinbefore referred to, which will enable the operator to shift the magazines to bring one or another thereof into position for use, without requiring the operator toleave his seat at the keyboard S. HOMANS,

of the machine, and to provide a structure of this class, which will not interfere with the installation and use of a side attachment for the machine, and particularly a side magazine attachment of the kind substantlally as shown and described in my prior Patent No. 1,321,744.

To these and other ends, the invention consists in certain improvements and combinations and arrangements of parts, all as will be hereinafter more fully described, the features of novelty being pointed out particularly in the claims at the end of specification.

In the accompanying drawing- Figure 1 is a side elevation of the upper portion of a typographical machine equipped with a magazine supporting and shifting structure, constructed in accordance with the preferred embodiment of the invention, the uppermost magazine being shown in operative position by the full lines, and the dotted lines showing the magazines tilted preparatory to a forward shift thereof;

Fig. 2 is a view similar to Fig. 1, but showing the intermediate or middle magazine in operative position;

Fig. 3 is a detail view of the mechanism which controls the shift of the magazines, the magazines being shown tilted preparatory to a rearward shift thereof;

Fig. 4 is a front elevation of the upper portion of a typographical machine of the linotype class, equipped with a'magazinc supporting and shifting structure embodying the present invention; and

Fig. 5 is a detail view in perspective of one of the controlling detents.

Similar parts are designated by the same reference characters in the several views.

The present invention is applicable to typographical machines generally, where a plurality of superposed magazines, shiftable to bring one or another thereof into operative position, are used, although the invention is especially applicable to typographical machines of the linotype class, wherein the superposed magazines normally occupy a forwardly and downwardly inclined position above the keyboard of the machine and at which keyboard the operator sits to manipulate the keyboard, and the other manuallyoperable or adjustable parts of the machine. The preferred embodiment of the Patented Feb. 15, 1921.

the

invention is shown in the accompanying drawings and will be hereinafter described in detail, but it is to be understood, however, that the invention is not restricted to the precise construction shown, as equivalent constructions are contemplated and these will be included within the scope of the claims.

In the present instance, the machine to which the invention has been applied, is of the linotype class and it comprises generally an upright main frame 1, in front of which is mounted the keyboard 2, the assembler 3, which is mounted in front of the main frame and above the keyboard, a supplemental upper stationary frame 1, and the magazines which are mounted above the main frame 1 and within the upper supplemental frame 4, the assembler 8 being arranged to receive the matrices delivered from the magazine which is placed in operative position, the delivery of the matrices being controlled by the keyboard 2, which actuates reeds or push-rods 5 which in turn act in the usual or well known way upon the matrix delivery escapements contained in the respective. matrix channels of the magazine. The operator customarily sits on a seat or chairin front of the keyboard throughout the operation of the machine.

In applying the present invention to a typographical machine of the type described, aframe or cradle 6 is provided, the front or rear ends of which rest on the top of the main frame, and this cradle is positioned and held against displacement by a pin 7 at each side thereof, which fits into a bore in the respective side of the frame or cradle 6 and also fits into a bearing 8, which is rigid, and forms a fixed part of the main frame. A set screw 9 may be fitted into the rear portion of the frame or cradle 6 and arranged to bear on the top of the main frame, to assist in mounting this frame or cradle 6 upon the main frame and to take up any slack that might otherwise existbetween it and the main frame so that when the frame or cradle 6 has been mounted and secured in position, it is rigid with and forms in effect a part of the main frame.

In the present instance, the magazine supporting and shifting structure is adapted to accommodate three matrix magazines M M? and M in superposed relation, these magazines being mounted for endwise insertion and removal upon the respective magazine frames C C and C The magazine frames C, C and C are connected along their opposite edges so that they remain in fixed relation to one another and, when shifted, they move as a unit. The magazines and their frames, when any one of the magazines is in operative position, occupy a downwardly and forwardly inclined position, and the lower or forward ends of the magazines are provided with escapements c which control the delivery of matrices there from, the reeds or push-rods 5 being adapted to coiiperate with the escapements of any one of the magazines, when suchmagazine isbrought into operative position. The escapements of the magazines prevent the discharge of matrices fromthose magazines.

The magazlne frames are slnftably mounted, according to the present invention, on

.an axis about which the magazines may rock or tilt, and this axls 1s shlftable 1n a forward and rearward direction to bring any one of the magazines into operatlve-positlon. Preferably and as shown, the frame or cradle 6 is provided at each side with a toothed rack of the gear segments being concentric with their axis ofrotation. llntoothed or smooth.

segments 14 are fixed to the sides of the gear segments so as to rotate therewith, the peripheries of the] segments 14 being concen trio with their axis of'rotation and in the pitch line of the teeth of the gear segments 13. The bars or tracks 11 have their upper surfaces on. the pitch line of the toothed racks 10 and the segments 14 are arranged to rest and to roll upon the tracks 11. By this construction, the segments 14, which support the magazines and the magazine frames, have a true rolling support on the tracks 11 and as the engaging surfaces of the tracks 11 and the segments 14 are on the pitch lines of the racks 10 and the gear segments 13, correct engagement of the teeth of the racks and gear segments is produced and maintained. From the construction thus far described, it will be understood that the magazines and their frames may be bodily tilted or rocked about the hubs 12 as an axis and also the magazines may be bodily shifted in a forward and rearward direction, owing to the rolling support afforded by the tracks 11 and cooperating segments 1.4:, the forward or rearward shifting movement of the magazines being utilized to bring a desired magazine into operative position, and the rocking or tilting motion serving to control the forward or rearward shift ofthe magazines. The hubs 12, which form' the axis about which the magazines and their fI'tIIl'hS tilt or rock, are preferably placed slightly in rear of the center of gravity of the structure comprising the magazine frames and the magazines mounted thereon, so that this structure will be nearly balanced, but will be; slightly over-balanced to the front of its axis.

The necessary tilting movements are imparted to the structure comprising the magazine frames and the magazines thereon by a handle 15, which is located immediately above but closely adjacent to the keyboard 2, the handle being connected to the magazine frames by a rod 16 which extends up wardly in front of the main frame 1 and in the present instance is fixed to one side of the upper magazine frame C preferably near its lower forward end.

The relative forward and rearward movements of the structure comprising the magazine frames and the magazines thereon are controlled preferably by segmental ratchets 17, which are fixed in the present instance to the outer sides of the gears 13, respectively, so that the ratchets will rotate in unison with the rotary movements of the gear segments, incident to forward and rearward movements of the magazine frames and the magazines. Each ratchet is provided with teeth or notches of a number corresponding to the number of magazines which the structure is designed to accommodatepeach ratchet in the present instance being provided with three teeth or notches 17 1'? and 17 corresponding to the three magazines M M and M teeth or notches of each ratchet are undercut, as shown, and a detent 18 is provided for each ratchet, each detent comprising a dog 19 which is pivoted on a stud 20, which is fixed to one side of one of the magazine frames, the magazine frame C in'the pres-.

ent instance, this dog being arranged to ride over the periphery of the ratchet 17 or to engage any one of the under-cut notches thereof, and the detent also comprises a controlling member 21 which, in the present instance, is in the form substantially of a bell-crank, one arm of which carries a pin 22 which projects at opposite sides of such arm, one end of the pin being arranged to bear against the side of the dog 19 which is remote from the ratchet, while the otherend of the pin 22 is arranged to cooperate with a controlling cam 23. The

- other arm of the bell-crank is connected to a spring 24: which acts to rotate the member 21 in a direction to press the pin 22 against the dog 19, and a torsion spring 25 which encircles the studs 20 connects the hub of the member 21 with the dog 19, this torsion spring acting to normally hold the dog 19 and the member 21 of the detent together, with the dog 19 pressed against or toward the pin 22, the latter then acting as a stop for the dog 19. When the detent is uncontrolled by the cam 23, the dog 19 will bear inwardly against the periphery of the respective ratchet 17, under the influence of the spring 24. Each cam 23,

- on the respective ratchet segment.

however, has a peripheral cam surface 26, upon which the outer end of the pin 22 on the member 21 is adapted to ride, and this cam surface is so shaped that when the cam 23 is set in a predetermined position, and the. structure comprising the magazine frames and the magazines thereon is tilted or rocked upwardly at its forward end, the pin 22 will be pushed outwardly, relatively to the ratchet, causing the member 21 of the detent to be rotated in a corresponding direction, the pin 22 being thus moved in'a direction away from the dog 19 and the dog will thus be disengaged from the periphery of the ratchet 17, after the end of the dog has been withdrawn from the under-cut notch in the ratchet. One of the cams 23 is arranged at each side of the structure comprising the magazine frames and magazines, and these cams are preferably fixed to the opposite ends of a shaft 27, which extends coaxially through and is rotatable in the hubs 12 on which the gear segments 17 are journaled, so that the two cams 23 will rotate in unison and will always occupy corresponding positions. One of the cams is provided with an extended arm 28, which bends in a direction downwardly and rearwardly and thence forwardly, to clear the parts of the main frame of the machine, and this arm is pivotally connected at 29 to a bar 30, which is provided at its forward end with a suitable handle 31, which is located adjacent to the keyboard of the machine and to the handle 15 and within convenient reach of the operator occupying his seat at the key board. The rod 30 is reciprocable in a forward and rearward direction through a guide 32 and this rod is adapted to occupy either of two positions, its forward position being determined by a notch 33 and its rear position by a notch 34, the bar being releasably or yieldingly retained in each of these positions by a spring plunger 35, which is adapted to cooperate with these notches. The position occupied by the bandle 31 determines the direction in which the magazines may be shifted, as will be hereinafter described.

Where, as in the present instance, the structure is adapted to accommodate three magazines, each ratchet segment 17 is provided with a tooth or projection 36, and a pawl 37 is pivoted at 38 to the respective upper supplemental. main frame member 4:. When the magazine structure is set to position the intermediate magazine M for use. as indicated in Fig. 2, the pawl. 37 will act as. a stop therefor, it then occupying a position immediately behind the projection 36 A latch 39 is pivoted at 4:0' to the lower magazine frame C this latch being acted on by a spring 4.1, one end of which is attached to the latch and the other end to a part of the lower frame C and a pin 42 serves as a stop for limiting the movement of the latch under the influence of the spring 41. The upper end of the latch 39 is formed with a hoolr 43 which is adapted to engage a lip 44 on the rear end of the pawl 37. A link 45 is pivotally connected at as to the latch and is provided at its forward end with a slot 17 in which operates a pin 48 carried by the respective cam 23. A collar 19 on each end of the shaft 27 is arranged to abut against the forward side of the respective frame member 4, and thus limit the rearward motion of the structure comprising the magazine frames and the magazines. A. projection 50 at each side of each magazine frame 'is adapted to rest upon the forward side of the frame or cradle (5 to limit the downward tilting motion of the magazine frames and their magazines and to sustain the overbalance of this structure at the front of the axis about which it tilts, as each magazine is brought into operative position.

The mode of operation of the magazine supporting and shifting structure constructed as hereinbefore described, is briefly as follows: Assuming that the uppermost magazine'llf is in operative position and it is desired to bring the intermediate magazine M into operative position, the handle 31 is pulled forwardly into the position shown in Fig. 1 and the handle 15 is swung upwardly, tilting the magazines to an extent somewhat greater than that indicated by the dotted lines in Fig. 1. This tilting movement of the magazines and their frames causes the dogs 19 of the detents to withdraw from the notches 17 of the ratchets and to ride up the peripheries of the respective ratchets, until they snap, under the action of theirsprings as, past the teeth 17 ,.the dogs 19 being free to do this because the cams 23, according to the position in which the handle 31 has been set, will be clear of the pins 22 of the respective detents. Thereupon the handle 15 is swung downwardly until'the projections 50 on the intermediate magazine frame C come to rest on the for ward edges of the frame or cradle 6. The downward swing of the magazines causes the dogs 19, which are then engaged in the under-cut notches or teeth 17 to rotate the ratchets 17 and with them the gear seg ments l3, and the latter in co liperation with the rack bars 10 cause the structure comprising the magazine frames and the magazines to shift forwardly, incidental. to the rolling or revolving movements thus imparted to the gear segments. In this way the intermediate magazine M is br ught into operative position and the detents will retain the parts in such position. If it is desired to bring the lowermost magazine M into operative position, the'handle 15 is swung upwardly,

as before, while the handle 31 occupies its forward positlon, the pawl 37 engaging the tooth 3b of the segmental ratchet to prevent rearward shift of the magazine supporting structure, and by which operation the dogs 19 of the detents will engage the undercut teeth or notches 17 of'the ratchet se ments 17, whereupon the handle 15 .is swung downwardly until the projections 50 on the frame C for the lowermost magazine come to rest upon the forward side of the frame or cradle 6, the downward swing of the magazine frames and the magazines causing the dogs 19 of the detents to rotate the ratchets 17 and with them the gearsegments 18, this further or additional rotation of. the gear segments shifting the structure comprising the magazine frames and their magazines forward. to their forward limit and thus bringthe lowermost magazine G into operative position. 7 7

ln order to shift the structure comprising the magazine frames and their magazines rearwardly, the following operations are performed. Assuming that the lowermost magazine o is in operative position, the handle31 is pushed to the rear or into the rear position shown in Fig. .2. The handle 15 is then swung upwardly, causing the gear segments 13 and the segmental ratchets 17,

the notches 17 of which are engaged by the dogs 19, to roll by gravity rearwardly until stopped by the engagement of the teeth 36 of the ratchets 17 with the respective pawls 37, whereby. the magazine supporting struclure is stopped in its intermediate position. Owing to the positionoccupied by the handle 31, the cams 23 will occupy such positions that during the upward movements of the detents, incident to the rearward roll of the segmental ratchets, the pins 22 will ride upon the peripheral cam faces ofthese cams and will tend to withdraw the dogs 19 from the notches 17 oft-he segmental ratchets 17. A. slightly-additional upward swing of the handle 15, while the magazinesupporting structure is held from rearward movement by the .pawls 37, causes the dogs 19 to disengage from the notches 17 of the ratchets, and the handle 15 may then be swung downwardly into the position shown in Fig. 2, the middle magazine 1/ 2 being thereby brought into operative position, the magazine supporting structure rocking, during this op eration, about the hubs 12, the projections 50 on the intermediate magazine frame C coming to rest on the frame or cradle 6. During this downward swing of the forward ends of the magazine frames and magazines, the dogs 19 of the detents will engage in the teeth or notches 17 of the ratchets, this be ing permitted by the riding of the pins 22 below andoff of the cams 23 and the final downwardtilting movement of the magazine frames and magazines causes a slight will carry the teeth 36 slightly forward of the forward ends of thepawls 37 the space thus provided between the teeth 36 and the pawls 37 permitting operation of the pawls without obstruction. In order to bring the uppermost magazine 1 1 into operative position, the handle 31 is pushed into its rearward position, as before, and the handle 15 is swung upwardly, as before. During this upward swing of the handle 15, and with it, the magazine frames and the gear segments 12 and the ratchet segments 17 will roll rearwardly by gravity, the dogs 19 during this movement being engaged in thenotches 17 of the respective ratchet segments, and the pins 22 on the detents will ride upon the peripheral cam faces of the cams 23, where-- by the dogs 19 will tend to pull out of engagement with the notches 17 The upward swing of the handle 15 and the magazine frames and their magazines also causes the latches 39 to swing downwardly and rearwardly, and during the downward and rear ward swing of these latches, the hooked ends 43 thereon pull down the lips 44: of the pawls 37, thereby lifting the forward ends of these pawls upwardly out of the paths of the teeth or projections 36 on the ratchet segments. The magazine supporting structure continues to shift rearwardly, incidental to the upward swing of the handle 15 and the rearward roll of the gear segments 12 and ratchet segments 17, until the collars 49 on the opposite ends of the transverse shaft 27 abut against the forward sides of the stationary frame members 4. A slightly additional upward swing of the handle 15 and magazines causes the dogs 19 of the detents to snap out of the respective notches 17 whereupon the handle 15, together with the magazine frames and magazines, may swing downwardly, thus bringing the uppermost magazine M into operative position, the lugs 50 on the uppermost magazine frame coming to rest on the cradle 6, and the dogs 19 coming into engagement with the notches 17 on the respective ratchet segments. The'final portion of the downward swing of the handle 15 and of the magazine frames and magazines causes the latter to move slightly forward, due to the engagement of the dogs 19 with the notches 17 thus disengaging the stop collars 49 from the frame members 4. The link 45 which connects the latch 46 with the cam 23 prevents rearward shift of the magazine frames and their magazines from the position shown in Fig. 2, when the intermediate magazine is in operative position, to a position to bring the upper magazine'M into operative position, 'unless the handle 31 occupies its rearward position, because if the handle 31 is in its forward position, the pin 1-8 will engage the rear end of the slot 47 in the link 45 and will push the latch rearwardly into disengaged relation with the pawl 37, and hence the latter will strike the tooth or projection 36 and thus prevent a rearward, shift, should the handle 15 be swung upwardly. This prevents a rearward shift of the magazines when the handle 31 is set for a forward shift.

The structure or unit comprising .the magazine frames and magazines may be rocked or tilted into a reversely inclined position as compared with that shown in Figs. 1 and 2, so that the magazines will be inclined in a direction downwardly and rearwardly. When the magazines have been tilted into such position, any one or more of the magazines may be removed and others substituted, in substantially the same manner as described in my prior Patent No. 1,115,031 in connection with the magazine supporting structure therein shown and described.

The present invention provides a novel and improved magazine supporting and shifting structure whereby a plurality of matrix storage magazines may be accommodated in the machine, and notwithstanding the considerable weight of this structure, the operator is enabled toeasily and quickly shift the magazines to bring any one of them into operative position, without the necessity of leaving his seat at the keyboard of the machine. Although the lifting of the forward ends of the magazines to clear the escapement actuating rods and the lowering of the said ends of the magazines to bring another magazine into cooperative relationtherewith involves the movement of a considerable weight and requires accurate registration, yet the operator is able to so tilt or rock the magazine supporting structure with ease and facility, it being noted that the axis about which the magazine supporting structure is tiltable is located substantially at, but sli htly to the rear of the center of weight thereof, so that the magazine supporting structure will be substantially balanced to enable it to be tilted or rocked easily, but is slightly over-balanced atthe front of such axis, in order that the weight of the forward end of the magazine supporting structure will serve to maintain the magazine which is in use, in operative position.
